Answer: hello your question lacks the options related attached below is the complete question

answer :

A brief positive current inward due to sodium entry through voltage gated sodium channels ( Option 4 )

Explanation:

What you would expect to see following the bathing of a sensory neuron in  tetra ammonium chloride and MgCl2, given that the voltage clamp moves from -70 to -5 mV is A brief positive current inward due to sodium entry through voltage gated sodium channels.

This is because as Cl^- enters the cells it causes the entrance of  Na^+ into the cell ( i.e. voltage gated Na^+ ions channels will open ) hence the mixture will cause a lower negative membrane potential to be present .

Flowering plants are a group of plants that have sexual reproductive organs called flowers, as well as leaves, stems, and roots.
Lelechka [254]

Which culturing method proivded the clearest results, the semisolid medium tube or the soft agar plate?
sattari [20]
The answer to this question would be soft agar plate.

The semisolid medium tube is mostly used for containing the specimen. It is hard to examine semisolid medium since the bacteria can grow in the upper part, middle part or even the lower part of the medium. In agar plate, the bacteria always growth in the upper part so it is easier to count the bacteria.
But semisolid can give some more information in determining whether the bacteria is anaerobic by looking for bubble inside the medium. Anaerobic bacteria can do fermentation that will produce air.
